4-Axis- An aggressive design that's eye catching and pretty unique. Very well done.
3-NelsonDesign-As always, yours is very creative and it's one sharp looking sketch, but I don't see how it works out as a BMW. Would work well as a Nissan.
3-TS-design- I like the glassy effect shading, but like Nelson's it doesn't look too much like a Beemer [at least not from the side view ].
